Answer:
Small, uncharged substances enter and leave cell membrane, the process Simple diffusion.
Option B
Explanation:
Cell membrane of the whole animal kingdom is made up of phospholipids bilayer with occasional protein floating in it. It also has some oligosaccharide molecules attached to outer side of membrane. This phospholipid has charged layer outside i.e. outer part is hydrophilic and inner part is hydrophobic.
So, when some uncharged molecule comes to the cell membrane, being uncharged it has no interaction with the cell membrane. Based on concentration gradient it can flow inside the cell membrane through different channel proteins.
